在这项研究中，我们调查了花生物学和访花昆虫区系在日本京都的6个雌雄异株的山胡椒属（樟科）的自然种群。山胡椒属植物的花在结构和花引诱剂方面相似，并且被广泛的昆虫访问。虽然典型的generalist授粉花，种间差异被发现在花访客组成。所有种类的山胡椒在生长季节的早期开花，从2月到5月。但不同种类的山胡椒开花高峰期是交错的。开花物候的轻微种间和性间分歧可能会减少种间异花授粉。本研究结果表明，传粉昆虫的种间分离与物候模式的季节性差异，而不是花引诱剂的字符位移。
In this study we investigated floral biology and flower-visiting insect fauna in natural populations of six dioecious species of Lindera (Lauraceae) in Kyoto, Japan. Flowers of the Lindera species were similar in structure and floral attractants, and were visited by a wide range of insects. Although typical of generalist-pollinated flowers, interspecific differences were found in flower-visitor composition. All species of Lindera flowered early in the growing season, from February to May. However, peak flowering periods of different species of Lindera were staggered. Slight interspecific and intersexual divergence of flowering phenologies may reduce interspecific cross-pollination. Results of this study suggest that interspecific segregation of pollinators was associated with seasonal divergence of phenological patterns, rather than character displacement of floral attractants.
